agentik-framework 0.1.7

Agentik — a CLI-first, modular agent framework that runs LLMs via OpenRouter.

Agentik Framework

Agentik is a CLI‑first, modular agent framework that runs LLMs via OpenRouter. It focuses on developer ergonomics: clean configs, a batteries‑included CLI, safe tool execution, rich transcripts with run metadata, and a dev profile with auto‑rerun watching for fast iteration.

---

Highlights

• CLI‑first workflow: agentik run, agentik dev watch, agentik tools ...

• OpenRouter integration: one key → many models

• Agent loop: plan → (optional tool) → reflect → finalize

• Pluggable tooling (via entry points) with built‑ins:

  • http_fetch — GET with caching + limits
  • html_to_text — HTML → text
  • write_file — safe file writer

• Policies enforced per tool call: allow_network, allow_filesystem

• Transcripts: JSONL with meta_start/meta_end (tokens, cost estimate, timings, tags)

• Run profiles: fast, thorough, deterministic, creative, cheap, dev

• Dev watcher: polling file watcher, auto‑rerun on save (no extra deps)

• Memory: file‑backed minimal memory (json or in‑memory dict)

---

Installation

Requires Python 3.10+.

pip install agentik-framework

# for local development
pip install -e .[dev]

OpenRouter API key

Set your key once (recommended):

PowerShell (Windows):

setx OPENROUTER_API_KEY "sk-or-..."
# then restart your shell

Or via Agentik RC:

agentik keys set openrouter sk-or-... --global

Verify your setup:

agentik self-test

---

End‑User Guide (PyPI + CLI)

Once you’ve installed the package from PyPI, you can use Agentik entirely from the CLI. Here’s a concise, step‑by‑step guide for end users.

1) Install

pip install agentik-framework

Python 3.10+ required.

2) Set your OpenRouter API key (one time)

Windows (PowerShell):

setx OPENROUTER_API_KEY "sk-or-XXXXXXXXXXXXXXXX"
# Open a new PowerShell window afterwards

macOS/Linux (bash/zsh):

echo 'export OPENROUTER_API_KEY="sk-or-XXXXXXXXXXXXXXXX"' >> ~/.bashrc
source ~/.bashrc

Verify:

agentik self-test
agentik models list --filter gpt --refresh   # optional network check

3) Create a project folder

mkdir my-agent && cd my-agent

Initialize a basic layout (templates are bundled with the package):

agentik init . --template basic --name "My Agent Project"

Generate a ready‑to‑run agent config (adds a file under agents/):

agentik new agent research --template basic --tools http_fetch,html_to_text,write_file --with-tests --to .

Want to see available templates and tools?

agentik template list
agentik tools list

4) Minimal config (if you prefer to paste one)

Create configs/agent.yaml with:

agent:
  name: ResearchBot
  goal: "Research and summarize information."
  loop:
    max_steps: 3
    reflect: true

llm:
  model: openai/gpt-4o-mini
  temperature: 0.3

memory:
  type: json
  path: ./memory/research.json

policies:
  allow_network: true
  allow_filesystem: true

tools:
  - http_fetch
  - html_to_text
  - write_file

5) Run your agent

Windows (PowerShell):

agentik run .\agents\agent.yaml `
  -p "Summarize the main differences between GPT-4o and small LLMs in 5 bullets." `
  --profile fast `
  --stream `
  --save-transcript .\runs\first-run.jsonl

macOS/Linux:

agentik run ./agents/agent.yaml \
  -p "Summarize the main differences between GPT-4o and small LLMs in 5 bullets." \
  --profile fast \
  --stream \
  --save-transcript ./runs/first-run.jsonl

Handy flags:

• --profile fast|thorough|deterministic|creative|cheap|dev|none
• --model <openrouter-model-id>
• --temperature <float>
• --save-transcript <path> — JSONL with metadata, tokens, timings, cost est.
• --tag, --note, --run-id — stored in transcript metadata

6) Use the dev watcher (auto re‑run on file changes)

PowerShell tip: quote your globs to avoid expansion.

Windows (PowerShell):

agentik dev watch .\agents\agent.yaml `
  --prompt "Summarize this project in 3 bullets." `
  --path . `
  --include '**/*.py' --include '**/*.yaml' --include 'templates/**' `
  --exclude '.venv/**' --exclude 'runs/**' `
  --save-transcripts .\runs `
  --profile dev `
  --stream

macOS/Linux:

agentik dev watch ./agents/agent.yaml \
  --prompt "Summarize this project in 3 bullets." \
  --path . \
  --include '**/*.py' --include '**/*.yaml' --include 'templates/**' \
  --exclude '.venv/**' --exclude 'runs/**' \
  --save-transcripts ./runs \
  --profile dev \
  --stream

7) Run tools directly (no agent loop)

agentik tools run http_fetch --arg url=https://example.com --arg ttl=3600 --arg allow_network=true --json
agentik tools run html_to_text --arg "html=<p>Hello</p>" --arg keep_newlines=true --json
agentik tools run write_file --arg path=out\hello.txt --arg "content=Hello" --arg allow_filesystem=true --json

8) Memory helpers

agentik memory init --type json --path .\memory\agentik.json
agentik memory recall --n 10 --config .\agents\agent.yaml
agentik memory summarize --n 20 --max-chars 1200 --config .\agents\agent.yaml

9) Batch prompts from a file

agentik batch run .\prompts.jsonl --column prompt --out .\results.jsonl --model openai/gpt-4o-mini

prompts.jsonl example:

{"prompt": "Write a haiku about summer."}
{"prompt": "One sentence on the solar eclipse."}

10) Common issues & fixes

“Network error talking to OpenRouter.” Check your key in the same shell: echo $env:OPENROUTER_API_KEY (PowerShell) / echo $OPENROUTER_API_KEY (bash). Try: agentik models list --refresh. If you’re behind a proxy, set HTTP_PROXY/HTTPS_PROXY.

Dev watcher says “unexpected extra arguments …” Quote your globs in PowerShell: --include '**/*.py' (with single quotes).

Not seeing new CLI features after edits? Reinstall in editable mode from your project root: pip install -e .[dev].

That’s it. After pip install agentik-framework you mainly interact through the agentik command. If you want examples or a minimal starter project scaffolded for you, just run agentik init and agentik new agent … and you’ll be up and running in minutes.

Quick Start

Initialize a project:

agentik init . --template basic --name "My Agent Project"

Scaffold an agent:

agentik new agent research \
  --template basic \
  --tools http_fetch,html_to_text,write_file \
  --with-tests

Create a minimal config (save as configs/agent.yaml):

agent:
  name: research
  goal: "Research and summarize web sources"
  loop:
    max_steps: 4
    reflect: true

llm:
  model: openai/gpt-4o-mini
  temperature: 0.2

memory:
  type: json
  path: ./memory/agent.json

policies:
  allow_network: true
  allow_filesystem: true

tools:
  - http_fetch
  - html_to_text
  - write_file

Run it:

agentik run .\agents\agent.yaml -p "Summarize the latest about OpenRouter rate limits"

  -p "Prompt text" \
  --prompt-file PATH \
  --path PATH \            # repeatable (default .)
  --include GLOB \         # repeatable (default python/yaml/md/templates/tools)
  --exclude GLOB \         # repeatable
  --interval 0.6 \
  --debounce 0.5 \
  --clear/--no-clear \
  --stream/--no-stream \
  --profile dev \
  --save-transcripts DIR \
  --obs-max-chars 800 \
  --no-initial-run \

Tools & Policies

Built‑in tools (selected):

• http_fetch(url, ttl, timeout, max_bytes, headers, allow_network) Returns {ok, data, error, meta} with data.text, data.status, and cache hints.

• html_to_text(html, keep_newlines, drop_links, max_chars) Lightweight HTML → text (dependency‑free).

• write_file(path, content, encoding, overwrite, allow_abs, allow_filesystem) Safe writer with sandboxing and system‑path guards.

Policies (YAML):

policies:
  allow_network: true
  allow_filesystem: false

If a tool requires a disabled capability, Agentik blocks it and records an observation.

---

Transcripts & Cost

Each run can append JSONL records via --save-transcript. Files include:

• meta_start: run id, profile, tags, agent, model, policies, memory path
• Tool calls and assistant responses
• meta_end: timings (planner/tools/reflect), tokens (prompt/completion/total), estimated cost

Cost is derived from OpenRouter pricing when available. You can override with env vars:

# USD per 1K tokens
$env:AGENTIK_PRICE_PROMPT_PER_1K = "0.50"
$env:AGENTIK_PRICE_COMPLETION_PER_1K = "1.50"
